Carrying Capacity Definition of Steel-Concrete Beams with External Reinforcement under the Fire Impact

Abstract

The authors proposed the results of fire resistance evaluation of steel-concrete beams with external sheet reinforcement at standard temperature range of fire in the room and justified specifications for flame-retardant coat due to design standards. In order to analyze fire resistance the three-dimensional computer models have been developed taking into account basic conditions of beams loading and bearing as well as non-linear "stress-strain" dependencies of concrete and external reinforcement.
